New to the board and wanted to see if I could get some advice for my existing build. About 9 years ago I decided to have RebirthAuto (St. Petersburg Florida) do the actual conversion on my 1975 BMW 2002. For the first few years, I drove it to work daily on a 30 mile round trip. However, since my work location changed, I wasn't able to make the round trip on a full charge anymore, so the car has been sitting in the garage with the exception of an occasional weekend run within the 30 mile range of the lead acid batteries. Now that the battery chemistry and technology has advanced, I am looking at replacing the LA batteries with newer chemistry batteries. I'd appreciate some advice on how best to proceed.
So here are some of the basics on the build:
- NetGain WarP9 motor.
- EVnetics Soliton1 controller with liquid cooling.
- 11 Deka Deep Cycle GEL 12VDC 97.6AH batteries (8 are mounted in the trunk and 3 in the engine compartment along with a service battery).
- Elcon PFC1500 charger.
-Iota DLS-30 DC/DC converter.
We kept the 4-speed manual transmission and Rebirth made an adapter from a single block of aluminum to mate the transmission and the Warp9 motor through the stock clutch/pressure plate.
Here are links to videos of the initial road tests:
Since RebirthAuto and EVnetics are no longer in business, I can't go back to them to do the battery conversion. Any suggestions on where to start would be appreciated.
